SC'ing an NA

[aero86]

this seems to be a topic that no one brings up. some, i looking for some opinions. what ive gathered is this..

using a stock SC and the NA crank pulley, id get about 4psi, close to the 5psi i am looking for.

i would need to get the following: SC, sc piping, sc manifold, bigger injectors, maybe a cheap wideband to tune.

alright, now that ive put that out there, what do you guys think?

I think life would be easier dropping an entire 4AGZE in !

Which is why no one talks about SCing their NA. And unless you're putting in the GZE low comp pistons, or the engine is in fantastic shape, you may* just be building a timebomb.


* Just because it may blow up is not by any means suggesting it will blow up, user experiences may vary.

i just dont understand why people will talk about turboing a NA when it seem simplier to just use the supercharger. am i wrong? if so, someone please let me know..

and yes, i realize it would be better to do a gze swap, but, ive already got a motor, and if all i have to do is swap a manifold, get all the piping and get some different injectors, it sounds easier than going turbo

The NA pistons are not forged like the SC. They are less likely to hold up to boost. When turboing an NA, the intake is preferrable for turbo than the SC intake. I would presume that turboing an NA would mean changing the pistons as well, but at least nothing else is really needed intake-wise. Besides, when turboing, there's going to be a good bit of custom work anyhow. Personally, from what I've read, turboing an SC would bea easier as long as the person had the NA intake stuff to bolt on. Since I haven't done it and don't understand fully how to do it though, I'm just relaying heresay I suppose. Good luck.

Difficulty wise, turbocharging or supercharging your NA is about the same. So you might as well go turbo and have a more efficient platform with more power potential.

Honestly, and this is coming from an SC owner, the only good thing about it is the massive power low in the revs and the novelty of saying that you have an SC. It does sound pretty sweet too... But what good is your 14 PSI out of an SC12 when it stops making good power after 6 grand which is where it turns into more of a hairdryer than a supercharger? That's when your turbocharged buddy is gonna fly by.

All that being said, I'm buying another chassis for my 4AGTE since I love this damned GZE so much.

i was just thinking this would take a lot less fab work since its mostly a bolt on affair. thats my reasoning behind it. i realize that this motor is now setup for boost, ive realized this. i just want a low boost level to up my power a little. i hardly drive it above 6k anyway, so i wouldnt be missing out on anything. the NA manifold would get in the way of the SC.

this topic has been brought up TOO MANY times already, maybe not on this forum but others. The GZE block is a better platform to start with when you plan on turbo/super-charging. A stock GZE block will hold up just fine with pretty high amounts of boost. The problem in making power usually is the restrictive SC12 or stock electronics. If you've seen people refer to turboing a 4A the chance they're using a GZE block is 99/100 unless they've done modifications to the internals of the engine.
What 86mister2, WIWhite87 and canadam have said is absolutely true.
If you want a supercharger, get the complete swap(block/head/intake/exhaust manifolds/electronics and wiring). Supercharing a 4AGE will be a waste of time/money and in the end may or may not turn out as reliable as a stock GZE setup. Save yourself the hassle and source out a complete swap if you so desire to have a supercharged 4A. It's not all that expensive.

i'd love to see a dyno sheet of the 200hp and a list of the mods
you'll have to do some fine tuning with a stand alone engine management system to pull off a high compression supercharger or turbo setup without blowing it up. rather be safe than sorry.

i will completely disagree with you. it's all in who does the work, i suppose. it also depends on who you listen to.

I want to see that list to, what do you have to do to make that kind of power without forced induction. I like the idea of all that power without the additional maint of a turbo or SC. I always feed my mk1(and other import cars) high-test gas anyway, they run alot better(mine's got over 200k,stock, still going strong)

is that butt dyno? or did you actually get on a chassis dyno? i call BS right now without a dyno chart. also, if you know how to do 200 whp in an na, why are you asking about how to supercharge an na? seems to me that someone who can build something to do 200hp on an na...yeah, i already said that...

[bspecmr2]

Oh please. Think about it. The people who ask if they can supercharge their NA 4AGE are 99% people who don't know much if anything about the process, so why not save them the troubles of finding out the hard way and get a complete swap. A person who's capable of building up a high comp Na setup with a supercharger or a turbo does not need ANY advice on this.

i just don't know what to say. ToyotaTechGeek is right - that's all BS. haha.
a V6 solara could not have taken you if you're really making the power you claim. for example - my stock 89 4agze mk1 took a 07 V6 solara (225hp, 240 torque and a 15.3@ 91mph). yes it was a close call through all gears but still ended ahead. mind you the stock SC makes roughly 145hp 135 torque at the flywheel. I'm not going to waste anymore time arguing about such a silly thing. you have no dyno or a list of mods to prove what your 4age is.

if you want to supercharge it, get the GZE intake manifold, fuel rail, injectors, intercooler and piping. Run a stand alone fuel management system as the stock electronics can't handle the high compression of the pistons and you'll go BOOM. good luck.

this is really kind of BS in that it is totally illegible without a cheat sheet for an attempt at understanding the gibberish on here. yeah, actually i am trained as an English teacher, so...
for what i decided i would trudge through, you guys have some really bunk ideas as (if i can understand correctly with the keyboard diarrhea) you state you wanted to turbocharge but opted not to since the compression was too high yet you want to supercharge instead. hello, boost is boost...
you need grammar and punctuation before you need boost. seriously.


BTW: in my weaksauce car, i pulled a V6 SC Solara from a dig to about 45 (which was the speed limit) and it was at 1.5 cars until the middle of 2nd gear. it was a buddy of mine who also managed to roast the snot out of his front tyres.

[GrammerBoy562]

i am not BS and your not helping why are you guys just putting me down? im just saying wat i knoe and wat i was told. and about my grammer or punctuation i dont give a damn wats on here this aint no skool easy report gosh! so forget all of this and all i said ill set it up with my people help. but thanks by the way.


BTW i knoe wat ive done and i knoe wat a little beast this is... i still dont understand why ok pplz. i bought the car like that and with a little help from my girl cousin he told me wat internals to get for the block. i knoew its hard to believe and i dont understand why so ill just drop it and fined a way to do it myself. thanks again. later!
